As discussed above, MIM114A and RIM114B comprise two II C bus 262A, 262B and 264A, 264B.II C bus is the two-wire polyphone bus of carrying out according to the industrial standard that the Philips semiconductor maker formulates.Inner II C bus 262A, 262B is used to processor in MIM and RIM, the communication between electricallyerasable ROM (EEROM) in MIM and RIM and the processor in power module.Primary processor operation in MIM is as the controller of two II C buses, in case MIM breaks down, the primary processor in RIM is born the effect of control as the controller of bus.Inner II C bus is used for transmitting communication and collection status information with other each processors by the primary processor among the MIM.Also have, state information and the setting of UPS 100 stored and comprised to primary processor in the MIM of electricallyerasable ROM (EEROM) is arranged.
In one embodiment of the invention, relay 280A and 280B are installed in the inside II C bus in the intelligent object.Each relay is controlled by the primary processor in including the intelligent object of relay.Relay is used to separate inner II C bus and the primary processor that allows to be installed in the intelligent object in the RIM groove at intelligent object component external and relay and is installed in the detection that electricallyerasable ROM (EEROM) among the RIM transmits information or finishes the autodiagnosis of its oneself II C bus and device.As above-mentioned described, the enforcement of II C only have one can the control bus communication control device and the MIM that is in operation in primary processor take on the bus master.In RIM, primary processor 250B can transmit information with electricallyerasable ROM (EEROM) 254B or finish oneself's detection of II C by unlatching relay 280B, claim the II C bus master of own conduct in RIM114A, transmit information by II C bus 262A then.In case communication is finished, primary processor 250B closed relay.
Processor on exterior I I C bus 264A, 264B are used the primary processor of permission in MIM or RIM and are installed in outside battery support is communicated with communication.Comprise switch at communication module, this switch coupling exterior I I C bus is to MIM exterior I I C bus 264A or RIM exterior I I C bus 264B.The state of switch is determined by the MIM status signal that MIM sends to communication module described above.Allow in MIM or RIM primary processor to become the bus master of exterior I I C bus at the switch on the communication module, rely on the running status of intelligent object to become the bus master of exterior I I C bus as MIM.
As described above, a large amount of different controlling schemes are used, allow MIM and RIM all to monitor the state of UPS, allow the suitable control UPS among MIM and the RIM, allow MIM and RIM all to receive from display apparatus module or by the instruction of communication module with the external device (ED) user of UPS transmission information.In one embodiment of the invention, MIM and RIM transmission information are mutually monitored mutual state and the data of UPS are provided mutually.
At each intelligent object 114A, 114B, electricallyerasable ROM (EEROM) are used to store setting and the parameter of UPS, and the primary processor in each module obtains in the information aspect beginning to start near electricallyerasable ROM (EEROM).In embodiments of the invention, electricallyerasable ROM (EEROM) can be used to storage system data running time, and the user exports the electric energy setting, the hardware calibration constant, and user password information and other user errors are provided with.
Each intelligent object also comprises stores memory 256A, 256B at random.Random asccess memory is used to store the operation setting that obtains from electricallyerasable ROM (EEROM) and about the current data of UPS operation, comprises the data that obtain from various perception lines and the data of being calculated by auxiliary processor and primary processor.In one embodiment of the invention, the memory of storage at random in each intelligent object comprises two sets of data, one sets of data is provided by the primary processor in same battery module and a sets of data is provided by the primary processor in other intelligent objects in UPS.As above-described, each among MIM and the RIM is coupled to the UPS line of induction and therefore can independently determines the state of UPS.If the purposes of two sets of data is to allow MIM and RIM comparing data and in two sets of data significant difference is arranged, remind the user mistake may occur.
Inner II C bus is used to also guarantee that when user's configuration data changed, the data that are stored among electricallyerasable ROM (EEROM) 256A and the 256B were consistent.Each MIM and RIM receive from user's lastest imformation of communication module and in one embodiment, no matter how to change when the configuration the user is provided with generation, can use the data updated in electricallyerasable ROM (EEROM).In this embodiment, the data of guaranteeing electricallyerasable ROM (EEROM) are identical, and only data updated is used to electricallyerasable ROM (EEROM) 254A in MIM and the electricallyerasable ROM (EEROM) 254B in RIM among the MIM.In one embodiment, the primary processor 250A in MIM provides updated information near the electricallyerasable ROM (EEROM) 254B in RIM to electricallyerasable ROM (EEROM) 254B by inner II C bus.
Also have other embodiments; in order to prevent wrong MIM to electricallyerasable ROM (EEROM) 254B input erroneous data, electricallyerasable ROM (EEROM) 254B adopts input protection directly to enter data into the electricallyerasable ROM (EEROM) 254B among the RIM to prevent MIM.When the primary processor 250A in MIM is an electricallyerasable ROM (EEROM) 254B new data more among the RIM, primary processor 250A by inner II C bus 262A to sending data at RIM primary processor 250B.Then, the primary processor 250B in RIM opens relay 280B and isolates II C bus 262B and II C bus 262A, imports in operation with to electricallyerasable ROM (EEROM) 254B as the bus master to allow primary processor 250B.In case the input to electricallyerasable ROM (EEROM) 254B data is finished, relay 280B closure and primary processor 250A become at this and are comprised in II C bus 262A, the bus master among the 262B.
Begin to start and in running at UPS, a large amount of programs is followed the function to guarantee that MIM on support and the intelligent object in the RIM groove are finished MIM described above and RIM, with guarantee when MIM breaks down, can be easy to be sent to the control of UPS 100 from MIM and RIM.Be coupling in control signal 272 between MIM and the RIM and be used to set up and pass between MIM and the RIM control UPS.The representation of these signals and the explanation of function are provided in the following table I.
Table I
The MIM/RIM control signal
| Signal name | Function in MIM | Function in RIM |
| IM+0_1 | Be coupling in earth point on the support, show that module is installed in the MIM groove | Coupling does not show that module is installed in the RIM groove |
| LPON | LPON and power module among the coupling RIM are used to start MIM and RIM in the mode of battery cold start-up | LPON and power module among the coupling MIM are used to start MIM and RIM in the mode of battery cold start-up |
| IM_OK | MOD_OK input port among the coupling RIM shows that MIM is " ok " | MOD_OK input port among the coupling RIM shows that RIM is " ok " |
| IM_PRES | MP_IN among the coupling RIM shows that module is in the MIM groove | MP_IN among the coupling MIM shows that module is in the RIM groove |
Once you begin start ups system 100, on the basis of signal IM0_1 state, intelligent object determines to be installed on which groove of UPS support at it.At first, relay 280A and 280B are used to prevent II C bus for open position, up to the running status termination of MIM and RIM.
Intelligent object experiences self-trace routine, if success, each module will be provided with the IM_OK signal and be " very ", provides control signal to show that MIM is for operation and state of a control to communication module and power module.In addition, the buffer 258A in MIM will have the output port that is authorized to as described above, provide from the control signal of buffer 258A and the output port that is closed in the buffer 258B among the RIM.When relay 280A and 280B opened, primary processor 250A and 250B read coupled electricallyerasable ROM (EEROM) 256A and 256B is that UPS obtains configuration information.Then, cut-off, the primary processor in MIM become inner II C bus 262A, the bus master of 262B.
If in the process that begins to start, MIM breaks down, RIM will can not receive the IM_OK signal from MIM then, and RIM will be under the control of UPS 100.In this case, primary processor 250B is moving as the bus master of inner II C bus, and communication module and power module react to receiving the signal from RIM.In addition, buffer 258B will have the mandate output port of oneself that control signal from RIM is provided.
In service at UPS, auxiliary processor is uninterruptedly finished pulse pong operation, the normal condition of main processor monitors processor in MIM and RIM.In one embodiment, this process is made up of to auxiliary processor and auxiliary processor feedback " 0 " primary processor transmission " 0 ".Then, primary processor sends " 1 ", and auxiliary processor feedback " 1 " is followed input state at primary processor for variable condition and auxiliary processor simultaneously, and this process will continue.If in this process, primary processor and auxiliary processor detect mistake, and mistake is detected then, and the IM_OK line is set to error condition.The intelligent object that breaks down also is changed to the control signal of power module and shows that intelligent object breaks down, if in MIM, also will be set to error condition to the state control signal of communication module.
If MIM breaks down, RIM detects this and breaks down so, and when the IM_OK line is in error condition, RIM is to be described the operation that the similar mode that occurs in when starting is taken over MIM as top.When the intelligent object that breaks down in the MIM groove is replaced by the intelligent object of operation, it sends request to guarantee the control to UPS by II C bus to RIM then.After the request of receiving, the intelligent object in RIM in the groove will be abandoned control, in case the intelligent object in MIM finds that control is abandoned, it will claim that the control signal of power module and communication module continues control UPS fully again.
In an embodiment of ups system 100, the feature that is described at present is incorporated among the UPS to prevent using start battery under the electric energy drop mode of no alternating current, the generation of battery drain.In existing ups system, under no AC energy drop mode, the representational continuation of logical circuit receives and allows the requirement of electric circuit inspection user to cold start-up from the voltage in the battery.Also have, in representational existing ups system, in electric energy drop mode process, capacitor and other devices are connected in parallel on the resistance, therefore cause battery slowly to leak.
In the embodiment of ups system of the present invention, relay and semiconductor switch are used to isolate the coupling of battery and any resistance, comprise electric heater and under the electric energy drop mode of no alternating current, all logical circuit electric energy decline is to prevent battery drain.In order to allow UPS to be recharged under this pattern, the cold start circuit has been added on power module and the intelligent object.Fig. 6 represents the cold start-up circuit and the function view of the control signal carried out on intelligent object 114 and power module 104.Discuss as above-mentioned, in embodiments of the invention, common intelligent object is used to MIM and RIM, is displayed on intelligent object among Fig. 6 and is to use representative as the configuration of the intelligent object 114 of RIM and MIM.
The part intelligent object that shows in Fig. 6 comprises primary processor 250, promotes push-button switch 302, auxiliary electric energy supply 304, and resistor 306-316, transistor 324-329, diode 331,332 and 333 is communicated with logical circuit 334.In one embodiment, promote that push-button switch is installed in the front of intelligent object (MIM and RIM) and when being moved, be easy to by the user approaching at the UPS Qianmen.The part intelligent object of representing in Fig. 6 comprises auxiliary electric energy supply 340, transistor 342,344 and 346, resistor 350-356 and diode 360.
Primary processor is applied to be communicated with logical circuit 334 to logical signal LPOFF.To the reaction of signal LPOFF, by resistance 306 and diode 332, voltage is applied in and is used to be communicated with transistor 327 on the transistor 327.When transistor 327 is connected, be grounded at the voltage that promotes on the push-button switch, at this moment, the user can disconnect the promotion push-button switch, because it is locked on the ground.
Primary processor detects not to be had alternating current at present and must use start battery.Primary processor is signalization LPON PSD height then, promptly by transistor 328 and 329, resistance 314,315 and 316 and diode 333 output signal LPON to 12 volt is set.Signal LPON is fed to each power module and other intelligent objects, will take place from the cold start of battery to notify these each modules.At intelligent object, signal LPON is received or passes on identical lead-in wire, depends on whether the special smart module is that it promotes button by one of user activated.When the LPON signal is received by intelligent object, signal is communicated with transistors 327 by diode 331 and resistance 313.When transistor 327 is connected, intelligent object charges with same way as described above.
On power module, LPON is applied on the transistor 342 by diode 360 and resistance 350 and is communicated with transistor 342.The connection of transistor 342 has inclined to one side resistance 352,353,354 and 355, causes that transistor 344 and 346 is communicated with.In case transistor 344 and 346 is communicated with, cell voltage is applied in the circuit on the power module, comprises that auxiliary electric energy supplies with 340 and the processor on power module, this can on the II C bus with MIM on primary processor transmit information.
Electric energy described above descends and the cold start circuit has important advantage than representative prior art ups system.Relay and transistorized use isolation resistance device can make in the mode of the use of the leakage that prevents battery and the cold start-up circuit that is described and to utilize the battery cold start-up, and not need maintenance can cause the logic electric energy of battery drain to be recharged state.
The present invention also has other embodiments, and the input current Managed Solution is performed in UPS 100, makes UPS 100 with low input ac voltage mode operation, and does not need to switch on the battery mode.As is well known, in the typical electronic device, comprise the device of UPS, when installing the input voltage reduction that can access, typical former because import the electric energy problem, the mobile rising of the electric current of device is imported electric energy in roughly the same level with maintenance.If it is too big that electric current moves increase, the circuit-breaker in UPS or on to the supply of UPS, may disconnect.In the device of typical UPS, if being reduced to, input voltage is lower than predefined level, UPS will switch on the battery mode and close input AC.This causes when AC energy and accesses, but is not in sufficiently high voltage levvl, has to move the battery shortcoming of (limited battery operation time).
In embodiment of the present invention, intelligent object is intended to detect low input (causing high input current) situation and reduces the whole electric current of UPS and move and make low input UPS operation and need not worry the open circuit circuit breaker.In one embodiment of the invention, be used in and finish this functional programs and say now and be described among Fig. 7 as a reference that this shows that electric current reduces program 400 flow charts.On the point 402 in this program, input voltage is detected and is transferred to primary processor by the auxiliary processor in MIM (if or RIM of breaking down of MIM).At definite piece 404, input voltage is compared with the boundary value of making an appointment.If input voltage is higher than this boundary value, program 400 runs to a little 402 so.
If input voltage is less than predefined boundary value, program enters into a little 406, input current detected and with predefined current margin value standard relatively.If electric current is less than boundary value, program turns back to a little 402, if electric current greater than boundary value, program enters into the point 408 that the less plan of electric current is done.In one embodiment of the invention, in order to reduce input current, send the charging current of instruction minimizing to battery at the controller on power module in control procedure of the primary processor on the intelligent object.The quantity that reduces can be fixed value or can be determined on the amount of current basis of the input port on the UPS 100.Also have in different embodiments, if excessively high at the electric current of input port, for some or all of power module, charging current can be reduced to zero.
The electric current minimizing is planned at point after 408 places are implemented, and program enters into a little 410, and here electric current is determined once more and compares with boundary value, and whether determine needs in the further minimizing program of electric current.If determine that piece 410 is output as "Yes", program further reduces inlet point 414 for input current so.Be output as "No" if determine piece 410, program entry point 412 so, need the minimizing of further electric current here or allow UPS to move any input voltage of extra electric current and electric current changes monitored.
In the present invention's electric current minimizing described above in the works, the charging current to battery module is reduced to allow UPS to move under low-voltage.In other embodiment, can be closed or after weighing, return the input current that reduces to UPS in other non-critical operations of UPS.
Describe as top theory, UPS 100 can be the UPS of branch phase place, and the UPS of described minute phase place can use two input phases of input electric energy system to charge and two output phases can be provided.For North America application, output voltage is set to 208 volts (phase place is to phase places), and the input phase typical case is that of phase line spends another skew 120.In minute phase place ups system, when the UPS by-pass switch is activated, need provide output phase and input phase to be complementary so that electric energy conversion stably to be provided to load.In typical ups system, the coupling of phase line is manually finished when installing by the electrician.
Will describe now, in an embodiment of ups system of the present invention, the phase line coupling is finished by ups system itself.As described above, the perception line is coupled from the I/O circuit 260A among MIM and RIM, and 260B is to input electric energy line 9 (seeing Fig. 5).In one embodiment, the I/O circuit comprises that zero-cross detection circuit auxiliary processor that is used to be coupled measures original phase angle between input phase.The phase angle of practical stability is determined by the primary processor in MIM and RIM.Primary processor in MIM (if MIM is in operation and is in the control) uses II C bus to collect from the original phase angle-data of MIM auxiliary processor.Also have, primary processor is transferred to primary processor among the RIM with the original phase angle-data at II C bus auxiliary processor from MIM in MIM.If the functional module in the MIM groove is not in the process of operation, the primary processor of intelligent object will become the effector of bus in the RIM groove so, and the original phase angle-data is transferred to the RIM primary processor from the RIM auxiliary processor.
The per 500 milliseconds of reception original phase angle-datas of primary processor effectively read generation up to ten times.If inner phase place lock ring dispatched with detected angle value be 120 degree, 180 degree or negative 120 degree add or reduce about 22 degree.It is zero that three continual invalid reading will be reset effective read value.Primary processor calculates phase angle actual between input phase as ten original mean values that read.Each primary processor passes to the auxiliary processor that it links to each other to the phase angle of its calculating.Auxiliary processor provides control signal to control the power module generation to power module the output voltage that is complementary with input voltage phase.The use that automatic phase detects stops prior art systems and uses the electrician that the needs of coupling are provided in the mode of trial and error.
As described above, in UPS 100, when preventing that UPS from providing the UPS element of the output electric energy of appointment to break down, the bypass relay can be activated and directly be coupled the input port of UPS to output port, and therefore bypass is set in UPS.At typical ups system, the hardware of amplitude limiter comparator was used to the limit of comparison output voltage waveforms upper and lower boundary value about quilt replenished, and this determines acceptable output voltage amplitude limiter up and down.Be arranged to the operation down of various output voltage for ups system, when output voltage is provided with change, hardware setting, bonding jumper, element or transducer are changed to adapt to amplitude limiter comparator up and down.
In at least one embodiment, be implemented in the software of amplitude limiter comparator intelligent object in UPS up and down in the present invention.By being implemented in the comparator of amplitude limiter up and down in the software, the boundary value limit can be defined by program and be used the scale constant of storing in electricallyerasable ROM (EEROM) 254A to correct by the intelligent object primary processor.Except more single voltage upper and lower boundary value limit, more comprehensively module is used to provide more optionally and intelligent comparison.In one embodiment of the invention, the boundary value of design comprises the value of determining in the form 2.
